If you suspect your pipes are clogged with grease or soap scum build-up (slow flow rates) it may be an indication to have the sewer lines jetted. Essentially this is a process by which high pressure water (3200 PSI) is run through the pipes, cleaning and clearing everything in it's path - grease, roots, wood debris, etc. Plumas Sanitation is equipped with jetters, service truck, and technician that can help you with these particular needs.
